Assortment of connectors used for wall joints
| Name and photo | Notes |
|---|---|
| punched flat profile | Element used in joints of walls made of the units of the same height. Replaces masonry bond. Can be used with traditional or adhesive mortars. |
| Winding flat profile | Element replacing masonry bond in the walls with thin bed joints. |
| Punched L-shape profile | Element for joints of masonry walls with reinforced concrete structure as well as for joints in walls made of the units of different heights. |
| Two-arm L-shaped profile | Element for joints of masonry walls with reinforced concrete structure or existing masonry walls, as well as for joints in walls made of the units of different heights. |
| Punched flat movement profile | Equivalent of the punched flat profile used in the locations where expansion joint must be introduced between the connected elements. |
| Punched L-shape movement profile | Equivalent of the punched L-shape profile used in the locations where expansion joint must be introduced between the connected elements. |
| Two-arm L-shaped movement profile | Equivalent of the two-arm punched L-shape profile used in the locations where expansion joint must be introduced between the connected elements. |
| truss | Prefabricated reinforcing beams composed of two parallel flat profiles connected with the sine-shaped rod. |
| Steel bars | Bar of the appropriate length assembled in the previously drilled hole. |
